GRIPPER-DISK FOR BINDERS.

Specification of Letters Patent.

Application filed November 17, 1914. Serial No. 872,604.

To all whom it may concern:

Be it known that I, RICHARD H. Moonn, a citizen of the United States,residing at Wakita, in the county of Grant and State of Oklahoma, haveinvented a new and useful Gripper-Disk for Binders, of which thefollowing is a specification.

; The present invention appertains to knotting mechanisms for binders,and more par ticularly to a twine gripper or holder.

Vith the customary twine gripper or holder now employed in the knottingmech- "anisms of binders, the notches of the disk become rounded andsmooth due to the wear and friction after continued use, which notinfrequently renders the gripper inefficient or inoperative, since thetwine hook will not properly hold the twine in the notches of the disk.

This invention contemplates the provision of a twine gripper or holderso formed, as to continue in its efficiency, notwithstanding the factthat the gripper becomes worn away in the continued use to which it issubjected, and whereby the common grippers or holders may be readilyaltered in accordance with the present invention, to increase the lifeand efiiciency thereof.

It is also within the scope of the invention, to provide simple andinexpensive means for increasing the life and efficiency of the gripperor holder, which will be thoroughly practical in use.

lVith the foregoing and other objects in view, the present inventionresides in the peculiar formation of the gripper or holder disk for thetwine, as hereinafter set forth in detail.

The invention is illustrated in the accompanying drawing, wherein Figurel is an elevation of one side of the gripper or holder. Fig. 2 is anelevation of the other side thereof. Fig. 3 is an enlarged sectionaldetail taken on the line 3-'3 of Fig. l.

The twine gripper or holder embodies the companion or complementarydisks 1 and 2, which are secured together in the usual manner, and eachof whichis provided with Copies of this patent may be obtained for fivecents each, by addressing the a series of peripheral notches 3,coinciding or registering with the notches of the opposite disk forcooperation with the usual twine hook (not shown).

In carrying out the present invention, the outer side of each of thedisks 1 and 2 is beveled around each notch 3, as at l, and the bevelededge a of each notch is provided with a series of oblique grooves 5forming the serrated edges 6 for the notches 3. The bevels 4 extend fromthe outer sides of the disks to the inner sides thereof, and the grooves5 extend to the edges of the bevels.

Vith the provision of the peculiar bevels and grooves it has been foundin practice, that notwithstanding the fact that the notches having theserrated edges become worn due to the continued friction to which theyare subjected, they will always effectively receive and hold the twine.In this manner, the life and efficiency of the gripper is materiallyenhanced, it being a frequent occurrence with the ordinary gripper 0rholder, for the same to become worn out and inelficient within a shortperiod due to the rounding and smoothing of the twine notches.

Having thus described the invention, what is claimed as new is A twinegripper for binders embodying a pair of parallel spaced disks securedtogether, the peripheries of the disks having coinciding curved notches,the outer sides 'of the disks being beveled around each notch, thebevels extending to both ends of the notches and extending from theouter sides to the inner sides of the disks, each bevel being providedfrom end to end with a series of grooves extending to the edges of thebevel, and said grooves being arranged obliquely.

In testimony that I claim the foregoing as my own, I have hereto aiiixedmy signature in the presence of two witnesses.
